types of dogs with black tongues
I REALLY need help with these genetic problems asapp please?
1. A rabbit, homozygous recessive for white fur, produces a little of eight bunnies. FOur of the bunnies are white and four are black. Set up a punnet square to determine the genotype of the father.
*i dunno how i would set this up, i really have no idea
2. The abilities to bark and to hold their ears erect are dominant traits in dogs. Keeping silent and having droopy ears are recessive traits. If a barking dog with erect ears (heterozygous for both traits) is mated with a droopy eared dog that keeps silent, what kinds of puppies can they produce?
*would the setup be like: RrRr * rrrr????
3. In humans, a widow’s peak is dominant and a straight hairline is recessive. Tongue rolling is dominant and the inability to roll the tongue is recessive. A male who is heterozygous for both widow’s peak and tongue rolling marries a woman who has a straight hairline and cannot roll her tongue. What type of children can they produce?
is *RrSs * rrss the setup??
please tx
1) You know the father is bb, 1/2 of the babies are also bb. You also know that of the other bunnies, they must have at least one b allele and because they are black, they must have one B allele. If the mother can give her babies one B or one b (remember the white babies received a b form daddy and a b from mommy), what must her genotype be?
2) For di-hybrid crosses you have two traits: Erect/droopy ears (Ee) and barking (Bb). a dog that is heterozygous for both will have an “E” and an “e” for the ears and a “B” and a “b” for its voice, so it will look like EeBb while the homozygous recessive will be eebb. The cross will look like this: EeBb*eebb
3) Yes that is the correct set up
